Tandem Solar Modules: One-Two Combination Packs a More Powerful Punch

Perovskite/ CIGS semiconductor pairing promises to boost photovoltaic efficiency

The efficiency ceiling of commercially available solar modules leaves little room for improvement. Tandem solar modules with two light-harvesting active layers have far greater potential. The future could well belong to this promising technology. Researchers engaged in the Capitano project are combining thin-film solar modules based on perovskite semiconductors with semiconductors made of copper, indium, gallium and selenium (CIGS). This combination is the key to building remarkably efficient tandem solar cells with all the advantages of thin-film technology and an efficiency factor that could top the 30-percent mark. The Karlsruhe Institute of Technology (KIT), the Schwäbisch Hall-based enterprise NICE Solar Energy, and the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) have joined forces in this project with the ZSW acting as coordinator.
